ATTACHMENT FOR TYPE- WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 559,571, dated May 5,1896.

Application filed February 15, 1894. erial No. 500,44l. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM E. DERRICK, of Palmyra, in the county ofWayne and State of New York, have invented a certain new and usefulImprovement in Attachments for Type-Writers; and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the drawings accompanying this application.

The object of my improvement is to provide means by which the positionof the printedlines on the paper are indicated to the eye withoutopening the machine and the proper margin is indicated at the top andbottom of the sheet.

To this end the invention consists of a scale provided with a series ofnumerals equidistant apart, corresponding with the printed lines andarranged in inverse order from l upward, said scale being mounted abovethe platen or cylinder in an inclined position, and forming a support tothe paper as it is fed up by the action of the machine, all ashereinafter described.

In the drawings, Figure 1 is a front elevation of a portion of atype-writer with my improvement attached. Fig. 2 is a cross-section ofthe same. Fig. 3 is a perspective View of the holder. Fig. 4 is anenlarged face view of the scale. Fig. 5 is an end view of the holder.Fig. 6 is an end view of the scale.

A indicates the platen or cylinder of a typewriting machine, which maybe any of the known kinds, that shown being the Remington.

B is the attachment, consisting of a standard a, secured to somestationary part b of the machine, and an arm a, which extendshorizontally over the platen.

O is a holder, consisting of a strip of metal with the edges turnedinward to form grooves to receive the scale. It is attached to a knucklecl,- fastened by a set-screw, by which means the holder can be adjustedto hold the scale. The construction of the attachment may be varied, asdesired, to adopt it to different kinds of machines.

D is the scale. It consists of a strip of cardboard, metal, or any othersuitable material, on which are marked at equal distances apart and atdistances corresponding with the lines to be printed by the machine aseries of numerals from 1 upward in inverse order,

commencing at the bottom, as shown in Fig. 4:. The scale is simplyplaced loosely in the holder, resting on a suitable stop at the bottomand in such position that the initial number 1 comes at a distance fromthe under side of the platen, where the printing is done, equal to thewidth of the desired margin to be left at the head of the sheet abovethe printing. In use the sheet is adjusted in the machine till its upperedge comes in line with the first number of the scale. This gives theproper margin at the head of the sheet. As the sheet is fed upward bythe printing process the upper edge runs over the scale and the positionof the printed lines on the sheet are exactly indicated by the numeralson the scale without opening the machine. The margin to be left at thebottom of the sheet is determined by knowing the number of lines on thesheet and by feeding the sheet up on the scale till its upper edgealines with the corresponding number thereon. As the sheets are ofstandard size, usually thirteen by eight, the printing can be done,leaving margins exactly corresponding in all the sheets and producinguniformity and beauty of appearance in the writing. In addition to theseadvantages the scale being set at an incline and standing above themachine, serves as a support for the paper and enables the printingto bedone more accurately and with less trouble.

Having described my invention, what: I claim as new, and desire tosecure by Letters Patent, is-- In a type-writing machine, thecombination of an arm attached to a stationary part and extending overthe platen, a knuckle on said arm adjustable to difierent positions, a

holder consisting of a metal plate attached to the knuckle and extendingabove the machine, and a scale provided with a series of numeralsarranged in reverse order resting in the holder, as shown and describedand for the purpose specified.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
